Abstract
Description
Die Erfindung betrifft ein Fahrzeug mit einem Biegequerträger und einer Stoßfängerverkleidung, wobei zwischen Biegequerträger und Stoßfängerverkleidung zumindest ein Absorberelement angeordnet ist, wobei das Absorberelement eine Nut aufweist, in welcher eine Schlauchsensorik zur Detektion eines Anpralles an die Stoßfängerverkleidung angeordnet ist.The invention relates to a vehicle with a bending cross member and a bumper cover, wherein between bender cross member and bumper cover at least one absorber element is arranged, wherein the absorber element has a groove in which a hose sensor for detecting an impact is arranged on the bumper fascia.
Zur Absorption kinetischer Energie, die bei einer Kollision des Fahrzeuges über eine Stoßfängerverkleidung auf eine Fahrzeugkarosserie wirkt, sind Absorberelemente zwischen Stoßfängerverkleidung und Fahrzeugkarosserie angeordnet. Heutige Fahrzeuge verfügen über eine aktive am Fahrzeug angeordnete Fußgängerschutzvorrichtung, die zu deren Auslösung eine Sensorik im Stoßfänger aufweist, mit der ein Unfall oder eine Kollision detektierbar ist.For absorption of kinetic energy, which acts on a vehicle body in a collision of the vehicle via a bumper cover, absorber elements between the bumper fascia and the vehicle body are arranged. Today's vehicles have an active arranged on the vehicle pedestrian protection device, which has to trigger their sensors in the bumper, with an accident or collision is detected.
Es ist ein Fahrzeug bekannt, welches einen Biegequerträger und eine Stoßfängerverkleidung aufweist, wobei zwischen dem Biegequerträger und der Stoßfängerverkleidung ein aus einem Schaum gebildetes Absorberelement angeordnet ist. In das Absorberelement ist an einer dem Biegequerträger zugewandten Seite eine Nut eingebracht, in welcher eine Schlauchsensorik, insbesondere zur Erfassung eines Fußgängeranpralles, angeordnet ist. Die Schlauchsensorik weist einen Schlauch auf, an dessen freiliegenden Enden jeweils ein Drucksensor angeordnet ist, wobei der Schlauch mit Luft und/oder einem anderen Medium befüllt ist und mittels der Drucksensoren eine aus einem Anprall resultierende Druckänderung in dem Schlauch erfassbar ist. Dabei sind die Drucksensoren und somit auch die freiliegenden Enden des Schlauches mit der Stoßfängerverkleidung verbunden.A vehicle is known, which has a bending cross member and a bumper cover, wherein an absorber element formed from a foam is arranged between the bending cross member and the bumper cover. In the absorber element, a groove is introduced on a side facing the bending cross member, in which a hose sensor, in particular for detecting a pedestrian impact, is arranged. The hose sensor system has a hose, at the exposed ends of each of which a pressure sensor is arranged, wherein the hose is filled with air and / or another medium and by means of the pressure sensors resulting from an impact pressure change in the tube can be detected. The pressure sensors and thus also the exposed ends of the hose are connected to the bumper fascia.
Der Erfindung liegt die Aufgabe zugrunde, ein gegenüber dem Stand der Technik verbessertes Fahrzeug mit einem Biegequerträger und einer Stoßfängerverkleidung anzugeben, wobei zwischen Biegequerträger und Stoßfängerverkleidung zumindest ein Absorberelement und eine Schlauchsensorik angeordnet sind.The invention has for its object to provide a comparison with the prior art improved vehicle with a bender cross member and a bumper fascia, wherein between the bender cross member and bumper fascia at least one absorber element and a hose sensor are arranged.
Die Aufgabe wird erfindungsgemäß durch die in Anspruch 1 angegebenen Merkmale gelöst.The object is achieved by the features specified in
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.
Bei einem Fahrzeug mit einem Biegequerträger und einer Stoßfängerverkleidung ist zwischen Biegequerträger und Stoßfängerverkleidung zumindest ein Absorberelement angeordnet, welches eine Nut aufweist, in welcher eine Schlauchsensorik zur Detektion eines Anpralles an die Stoßfängerverkleidung angeordnet ist. Erfindungsgemäß weist das Absorberelement zumindest zwei Teilbereiche auf, wobei ein erster Teilbereich aus einem härteren Material gebildet ist, als ein zweiter Teilbereich und der erste Teilbereich zwischen der Stoßfängerverkleidung und dem zweiten Teilbereich angeordnet ist.In a vehicle with a bending cross member and a bumper cover, at least one absorber element is arranged between the bending cross member and the bumper cover, which has a groove in which a hose sensor system for detecting an impact on the bumper cover is arranged. According to the invention, the absorber element has at least two partial regions, wherein a first partial region is formed of a harder material than a second partial region and the first partial region is arranged between the bumper cover and the second partial region.
Dadurch, dass das Absorberelement die zwei Teilbereiche aufweist und der erste Teilbereich härter ausgebildet ist als der zweite Teilbereich, ist es in besonderes vorteilhafter Weise möglich, länderspezifischen Anforderungen hinsichtlich einer Steifigkeit des Absorberelementes, aber auch einer erforderlichen weniger hohen Steifigkeit zur Erfassung eines Anpralles an die Stoßfängerverkleidung mittels der Schlauchsensorik gerecht zu werden.Due to the fact that the absorber element has the two partial regions and the first partial region is harder than the second partial region, it is possible in a particularly advantageous manner to meet country-specific requirements with regard to rigidity of the absorber element, but also a required less high rigidity for detecting an impact on the absorber element To meet bumper trim using the hose sensor technology.
Die Schlauchsensorik ist besonders bevorzugt Bestandteil einer Fußgängerschutzvorrichtung, die als mittels erfasster Signale der Schlauchsensorik aktivierbares Fußgängerschutzmittel eine aktive Motorhaube und/oder einen Fußgängerairbag aufweist.The hose sensor system is particularly preferably part of a pedestrian protection device which has an active hood and / or a pedestrian airbag as pedestrian protection means activatable by means of detected signals of the hose sensor.
